SPECIFICATION forming part of Letters Patent No. 733,386, dated July 14., 1903.

Application filed oqtober 22, 1902. Serial No. 128,285; (No model.)

To (tZZ whom it may concern:

Be it known that I, MAJOR Goonwin, J r., a citizen of the United States, and a resident of Wareham, county of Plymouth, State of Massachusetts, have invented an Improvement in Cop Carriers or Spindles for Loom- Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of a novel, simple, and efficient cop carrier or spindle for loom-shuttles, the construction and arrangement being such that the yarn of the cop is not weakened by the act of placing it on the spindle, the drag is reduced when the yarn is woven off down to the base or bottom portion of the cop, and the amount of waste is reduced to a minimum.

Cops are wound on short paper tubes or the like and are spun on bare spindles, so that when the completed cop is dofied it has a longitudinal hole or bore extending therethrough. In order to use such cops in loomshuttles, it is now customary to employ a split skewer or spindle, onto which the cop is forced, the normal diameter of the skewer being greater than that of the spindle on which the cop was spun. Such forcing of the cop onto the skewer weakens the yarn by stretching it unduly, and often the edges of the skewer will rupture or break the inner layers of yarn around the bore of the cop. Such weakening of the yarn causes the majority of breaks when the cop is pretty well woven off, and in addition the drag of the yarn at such time causes breakage, as the base or bottom portion of the cop is so near the head of the spindle, the yarn being obliged to draw off over the greater part of the blade. By my invention 1 obviate breaks due to such causes, and not only that, but I am enabled also to reduce waste to a minimum, because after the cop has been applied to the carrier or spindle it cannot be pulled off, and it is easier for the operative to weave off substantially the entire cop rather than to attempt to cut off the portion forming the base thereof.

The various novel features of my invention will be fully described in the subjoined specification, and particularly pointed out in the following claims.

Figure 1 is a view in side elevation and section of a cop carrier or spindle embodying my invention applied to a loom-shuttle and with a cop in position, the side ofithe shuttle being broken out. Fig. 2 is a similar view of the cop-carrier, the shuttle being omitted and showing the base or bottom portion of the cop as having been moved toward the tip of the carrier; and Fig. 3 is a side elevation of a cop-carrier embodying my invention applicable for use in shuttles with automatic filling-replenishing looms.

Referring to Fig. 1, the shuttle S, of usual construction, is provided witha seat 8 and overhanging spring s 'to cooperate with the sustaining-head a of the cop carrier and spindle, the head being pivotally connected with the shuttle by a fulcrum-pin a The head has rigidly attached thereto a blade, which is cylindrical, as at b, from the head to an annular shoulder b and the latter is shown herein as somewhat nearer the tip of the blade, the latter from the shoulder tapering, as at b, to the tip and being substantially the size of the spindle on which the cop was spun. A cop-tube carrier, shown as a sleeve d, is slidably mounted on the cylindrical part Z) of the blade, said sleeve being of such external diameter as to readily enter the coptube c of the cop C and a little longer than the cop-tube, said sleeve having an annular enlargement d at its inner end to form a stop or abutment for the cop-tube when applied thereto. A spring 25 is interposed between the head CL and the nearer end of the sleeve and surrounding the blade, the spring tending to move the sleeve toward the tip of the blade, such movement being limited by the shoulder b as shown in Fig. 3.

In Fig. l a full cop O is represented on the cop carrier or spindle, and when the cop is to be applied it is pushed easily onto the blade until the cop-tube passes over the sleeve d and abuts against the enlargement d. The cop is then pushed toward the head a,thereby sliding the sleeve along and compressing the spring, the sleeve at the same time uncovering the cylindrical portion of the blade between it and the shoulder b As soon as this part is exposed the yarn around the bore of the cop contracts aroundit, hugging the cylindrical. part of the blade, as shown in Fig. 1,

adjacent the shoulder b the latter preventing withdrawal of the cop, which is then ready for use. Inasmuch as the tapered part b of the blade is substantially the size of the spindle on which the cop was spun, it will be manifest that the bore of the cop will not be stretched, and as the biade is solid and smooth there are no edges presented tending to cut or rub the yarn. As soon as the yarn is Woven off down to and beyond the shoulder b the spring 25 begins to expand, pushing the sleeve (Z and the remaining yarn mass toward the tip of the blade, and thus decreasing the distance between the delivery end of the cop and the blade tip. This greatly diminishes the drag on the yarn and obviates yarn breakage due to drag in weaving 01?. As the yarn is woven off the outer end of the sleeve continues to approach the ietainingshoulder and finally reaches it, the bottom or base of the cop then being as near as possible to the tip of the blade and near enough to effectively reduce the drag while the balance of the yarn is woven oif.

Weaverswill frequently pull the base of a cop off a cop-skewer when there is too much yarn thereon for waste rather than to weave it 0%; but my invention prevents this practice, as the base of the cop cannot be pulled 01? while there is too much yarn remaining for waste. The weaver would be obliged to cut it off, and this would take longer than it would to weave off the yarn remaining, so that by myinvention I reduce waste to a minimum.

In Figs. 1 and 2 the cop carrier or spindle is shown of the type adapted to be permanently mounted in the shuttle; but in Fig. 3 I have shown a modification of my invention, adapting the same for use in self-threading shuttles employed in automatic filling-replenishing looms of the type wherein the running shuttle is provided with fresh filling when necessary. The blades b I), having the retaining-shoulder b the cop-tube holder cl, and spring 25 a e substantially as described; but the head a is cylindrical and provided with annular ribs, shown as split rings a to be engaged by the holding-jaws in the shuttle, one such shuttle being shown in United States Patent No. 574,864, dated January 5, 1897.

My invention is not restricted to the precise construction and arrangement herein shown, for so far as I am aware it is broadly new to provide a non-expansible cop carrier or spindle with means to automatically move the cop toward the tip of the blade when woven oif to the lower half of the cop. It is also broadly new, so far as I am aware, to provide a yieldingly controlled support or holder for the cop-tube slidably mounted on a non-expansible or solid blade, the positioning of a cop operating to permit retaining means to engage the interior of the cop and hold the same upon the blade of the cop-carrler.

Various changes or modifications may accordingly be made by those skilled in the art without departing from the spirit and scope of my invention, one practical embodiment whereof is herein illustrated and explained in detail.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cop carrier or spindle for loom-shuttles, a solid blade of substantially the size of the bore of the cop, a continuous, annular device integral with the blade to interiorly engage the cop and retain it on the blade, and means mounted on the blade back of said device to support the cop-tube and move the same toward the tip of the blade as the yarn is woven off the cop.

2. A cop carrier or spindle for loom-shuttles, comprising a solid blade adapted to readily enter the bore of the cop, an annularcopretaining shoulder on the blade, the blade being tapered from the shoulder to the tip and cylindrical and reduced in diameter from the shoulder toward the opposite end of the blade, and means to automatically move the base of the cop toward the tip of the blade as the yarn is woven off below said shoulder.

3. A cop carrier or spindle for loom-shuttles, comprising a solid blade adapted to readily enter the bore of the cop, an annular, continuous cop-retaining shoulder on the blade, and a spring controlled sleeve abutting against the shoulder when the cop-carrier is empty and adapted to receive the cop-tube and move the base of the cop toward the tip of the blade when the yarn is woven off to said shoulder, the latter being exposed to engage the interior of the cop and hold it in position when the sleeve is moved away by the application of the cop.

4. A cop carrier or spindle for loom-shuttles, comprising a blade solid from head to tip and having a sustaining-head, a springcontrolled sleeve for the cop-tube, longitudinally movable on the blade, and means on the latter to limit outward movement of the sleeve and to engage the inner winding of the cop when the latter is placed upon the blade, to retain the cop thereon and maintain the sleeve near the head, winding off of the yarn to and beyond the retaining means permitting the sleeve to gradually move the yarn forming the base of the cop forward toward the tip of the blade.

5. A cop carrier or spindle for loom-shuttles, comprising a blade solid from head to tip and having a sustaining-head, a springcontrolled holder for the cop-tube slidably mounted on the blade, and a continuous annular shoulder on the latter beyond the outer end of the holder, the blade being reduced in diameter between the shoulder and the head, the positioning of a cop upon the blade pressing the holder toward the head to expose the reduced portion of the blade back of the shoulder and permitting the yarn in the bore of the cop to contract and engage such exposed portion of the blade between the shoulder and the holder, to retain the cop upon the blade.

6. A cop carrier or spindle for loom-shuttles, comprising a solid blade having a sustaining-head, and an annular, cop-retaining shoulder, the blade being reduced in diameter back of the shoulder, a slidable sleeve on the reduced portion of the blade between its shoulder and head, and a compressible spring interposed between the head and sleeve, the positioning of a cop, on the cop-carrier moving the sleeve to expose the shoulder and permit it to engage the interior of the cop, and compressing the spring, the expansion of the latter when the yarn is woven off below the shoulder moving the sleeve and the re- MAJOR GOODWVIN, JR.
